Civilization V map generator

For the last few weeks Civilisation V always generates the same kind of boring map: flat land, very few mountains, most of the land desert or tundra. Is there anything that could have caused this? I have not installed any mods or modified the game in any way.

Solution 1:

Did you configure it to be arid and old; or random for everything and just have a run of similar worlds?

You could explicitly set the World Age and Rainfall (from your description, the temperature could have varied a bit) to mix it up.

• World Age: Adjusts the map "smoothness", as a longer world has eroded more.
  • 3 billion years: highly mountainous
  • 4 billion years
  • 5 billion years: flat
• Temperature:
  • Cool: more ice, more tundra at lower latitudes
  • Temperate
  • Hot: more jungles, less tundra
• Rainfall:
  • Wet: more forests and jungles
  • Normal
  • Arid: more deserts

Configure the settings to a younger earth (3 or 4 Gyr) and temperate or wet rainfall if you want to get away from what you're describing. You can do so on the "Advanced Setup" panel when you configure a game.
